Fuel low pressure temp sensor plausibility
1. Check the fuel temperature sensor connectors and cable harness. 2. Check that the ambient temperature sensor T27 connected to the ICL shows a reasonable value. 3. Check that the coolant temperature sensor T33 shows a reasonable value. 4. Replace the fuel temperature sensor T118 To invalidate the fault code: Leave the engine off and wait until the coolant temperature and the ambient temperature are the same.Then control that the fault code is invalidated.
What you'll see
No driver-visible symptom recorded.
System reaction
Can affect gear changing performance.
Diagnostic depth
The fuel temperature sensor T118 shows an unreasonable value. The difference is too large between the temperature from the fuel temperature sensor T118, the coolant temperature sensor T33 and the ambient temperature sensor T27,
Possible causes: • Fault in the fuel temperature sensor connectors or cable harness. • Fault in the ambient temperature sensor T27, connected to the ICL • Fault in the coolant temperature sensor T33 • Fault in the fuel temperature sensor T118
